Medics restarted his heart, but he was placed in an induced coma and doctors decided, along with Richter, the damage to his leg was so severe they needed to amputate the lower portion of it.

A message on the club's website yesterday read: "Jonathan's progress means a lot to the Richter family, friends and all involved with FC Nordsjaelland, but the family now request that all continue to respect the peace that Jonathan needs in the future as he faces tough rehabilitation."

He was reportedly recovering well from the operation and was expected to be moved out of intensive care shortly.
